SPECIFICATION forming part of Letters Patent No. 709,221, dated September 16, 1902.

Application filed December 16, 1 901. Serial No. 86.006- (No model.)

To all whom itmayconcern:

Be it known that I, DAVID E. HUNTER, a citizen of the United States, and a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented new.

, and useful Improvements in Folio-Holders,

of which the following isa specification.

My invention consists in improvements in folio-holders, and is adapted especially to trate an embodiment of my invention, Figure 1 is a top plan view of a drawer containing my improved folio-holder. Fig. 2 is a longitudinal vertical section of the d rawer of Fig. 1. Fig. 3 is a detail, on alargerscale, of the adjustable hinge which forms part of my device;

and Figs. 4: 5, and 6 are details showing the self-adjusting silent-acting securing device which constitutes part of my improvements. The folio-holder consists of the cover-board P, which is hinged at 1:) at the end of the plied to such a drawer.

hole h drawer or case A.

Folio-holders ofthe character herein described are especially useful in drawers commonly used in the display of photographs and the like, and I show my invention herein ap- As the load in the drawerinoreases in bulk the hinge connection of the cover-board P should be susceptible of adjustment, so that the cover-board P may always lie parallel 'with the bottom of the drawer A. I secure this adjustment by the hinge device shown in detail'in Fig. 3. The hinge-plate h is secured to the cover-board P and is articulately joined to the block it at The block it is perforated to receive a slide-rod h which is secured to the front board of the drawer A at 72. and steps in the Aclutch-block 71, depends from the block h upon a screw it", the clutch-block 72. being tapped for the purpose and the screw h turning idly and loosely in a cylindrical hole in the block 71.2. The upper end of the screw 71. is squared to receive a key-wrench. .An incline 77. is formed upon a depending portion of the block 71, and the end of the clutch-block 72. adjacent thereto is correspondingly beveled. Thehole for the sliderod 72, is at its lower end partly cut from the block W and partly from the clutch-block 7L5. If it he desired to raise or lower the hinge for the board P,the screw it is slackened by means ofa key-wrench, and the clutch-block 7L5 hangs loosely, permitting the block b to slide freely on the rod h to the desired position. Then the screw h is turned up tight, and the clutchblock is drawn up and toward the rod it by means of the incline or wedge Wand securely binds the hinge.

It is also necessary to fasten the upper or rear end of the cover-board P at points suited to the thickness of the contents of the drawer A. Pawl-and-rack fastenings as usually constructed will accomplish this result; but they are noisy and ill adapted, therefore, to library use, for which my improved drawer is espe .cially intended. I provide, therefore, the silent automatic pawl-and-rack arrangement shown in Figs. 4 to 6, inclusive. A block B, Fig. 4, is secured to the center of the back of the drawer A, and thereon is mounted the rack b. The toothed portions 19 are separated by a track or channel 19 which is per fectly smooth. The pawl is mounted on the pawl-plate m, secured to the cover-board P, which is slotted at m to accommodate the pinguide m and the Wings n of the plate m. The pawl 07. is mounted on the pin a which passes through and between the wings m. The pawl 91. is slotted at 12 so that its connection with the pin 12 is loose. The pawln is provided with three projecting portionsthe thumb-plate it, the dog a and the shoe n. A pin m which slides in the pin-guide m and the hole mflcut in the cover-board P, is pressed against the pawl n by means of the springm. which is seated in the hole m This pin m keeps the pawl n constantly thrust outward, so that as the cover-hoard P is closed up, as from the position P of Fig. 2, the shoe it strikes the rack-plate b first. This shoe n registers with the smooth track 19 and slides therein noiselessly and with enough friction to keep the dog a out of contact with the, racks b When the cover-board P has been pressed into closed position and the hand of the person manipulating it is withdrawn, the natural elasticity of the contents of the 7 drawer causes the board P to rise a little.

' This movement makes the shoe n take hold 1. The combination, in adrawer, ofa hinged cover-board, and a securing device therefor consisting of a pawl, a rack therefor, a track,

a pawl-shoe running in the track and adapted by contact therewith to hold the pawl away from the rack as the cover-board is closed, substantially as described.

2. The combination, in adrawer, ofa hinged cover-board, and a securing device therefor consisting of a pawl, a rack therefor, a pawlspring, normally urging the pawl toward the rack, a track, a pawl-shoe running in the track and adapted by contact therewith to hold the pawl away from the rack as the cover-board is closed, substantially as described.

3. The combination, in adrawer, ofahinged cover-board, and a securing device therefor consisting of a pawl loosely pivoted to the cover-board, a rack therefor,'a track, a pawlshoe running in the track, and adapted by contact therewith to hold the pawl away from the rack as the cover-board is closed, substantially as described.

5. The combination, in a folio-holder, of a cover-board. a hinge-plate thereon, articulately joined to a sliding block, said block perforated to slide on a rod, the rod, a clutchblock pendent from the sliding block upona binding-screw, and located between the sliderod and an incline formed upon the sliding block, substantially as described.
